摘要: Methods are provided for manufacturing a cyclic urea adduct of an ethyleneamine compound, the ethyleneamine compound being selected from the group of ethyleneamines and hydroxyethylethyleneamines and comprising at least one —NH—CH2-CH2-NH— moiety and at least two ethylene moieties, wherein the ethyleneamine compound is reacted with CO2 in the presence of an auxiliary compound selected from ethylenediamine (EDA), monoethanolamine (MEA) and mixtures thereof, the molar ratio of auxiliary compound to amine compound being at least 0.02:1. It has been found that the presence of an auxiliary compound selected from ethylenediamine (EDA), monoethanolamine (MEA) and mixtures thereof leads to a substantial increase of the reaction rate as compared to a process wherein the auxiliary compound is not present.

摘要: A process is provided for converting cyclic alkyleneureas into their corresponding alkyleneamines. The process includes, in a first step, converting cyclic alkyleneureas into their corresponding alkyleneamines by reacting cyclic alkyleneureas in the liquid phase with water with removal of CO2, so as to convert from about 5 mole % to about 95 mole % of alkyleneurea moieties in the feedstock to the corresponding amines. The process further includes, in a second step, adding an inorganic base and reacting cyclic alkylene ureas remaining from the first step with the inorganic base to convert them partially or completely into their corresponding alkyleneamines. Certain embodiments of the two-step process obtain a high conversion of cyclic alkyleneureas, while using substantially less strong inorganic base. Certain embodiments of the process process also show a higher selectivity to amines than prior art processes.
